ABSTRACT

The invention relates to trifluoromethyl sulfonyl and trifluoromethyl sulfonamido compounds and the physiologically acceptable salts and the prodrugs thereof. These compounds are expected to modulate the activity of protein tyrosine enzymes which are related to cellular signal transduction, in particular, protein tyrosine phosphatase, and therefore are expected to be useful in the prevention and treatment of disorders associated with abnormal protein tyrosine enzyme related cellular signal transduction such as cancer, diabetes, immuno-modulation, neurologic degenerative diseases, osteoporosis and infectious diseases. The invention also relates to the use of compounds containing fluoromethyl sulfonyl groups as phosphate mimics. These mimics may be used to inhibit, regulate or modulate the activity of a phosphate binding protein in a cell.

RELATED APPLICATIONS

[0001] This application is related to U.S. Provisional Application Serial No. 60/150,970, filed Aug. 27, 1999 and U.S. Provisional Application Serial No. 60/165,365, filed Nov. 12, 1999, which are incorporated by reference as if fully set forth herein.

FIELD OF THE INVENTION

[0002] The present invention relates to, inter alia, novel trifluoromethyl sulfonyl and trifluoromethyl sulfonamido compounds, their physiologically acceptable salts and prodrugs, which modulate the activity of protein phosphatases and uses thereof. The invention also relates to the use of compounds containing fluoromethyl sulfonyl groups to treat certain diseases. These compounds may be used as phosphate mimics to inhibit, regulate or modulate the activity of a phosphate binding protein in a cell. Thus, these mimics may be particularly useful in the treatment of phosphate binding protein associated disorders.

BACKGROUND OF THE INVENTION

[0003] Phosphate derivatives are involved in a wide variety of cellular processes. Common phosphate derivatives include nucleotides (e.g. mono-, di- or tri-phosphate adenosine, guanine, cytosine, thymidine, or uridine, or cyclic derivatives) either naturally occurring or synthetic analogues. Other common cellular phosphate derivatives include co-factors such as thiamine pyrophosphate, NADPH, pyridoxal pyrophosphate, or coenzyme A; compounds involved in sugar metabolism such as glucose 6-phosphate, fructose 6-phosphate, compounds involved in fatty acid metabolism such as glycerol 3-phosphate; compounds involved in lipid biosynthesis such as isopentyl pyrophosphate, geranyl pyrophosphate or farnesyl pyrophosphate.

[0004] Signal Transduction

[0005] Another area involving phosphate binding proteins is cellular transduction. Cellular signal transduction is a fundamental mechanism whereby external stimuli that regulate diverse cellular processes are relayed to the interior of cells. The biochemical pathways through which signals are transmitted within cells comprise a circuitry of directly or functionally connected interactive proteins. One of the key biochemical mechanisms of signal transduction involves the reversible phosphorylation of residues on proteins. The phosphorylation state of a protein may affect its conformation and/or enzymatic activity as well as its cellular location. The phosphorylation state of a protein is modified through the reciprocal actions of protein kinases and protein phosphatases at various specific residues.

[0006] A common mechanism by which receptors regulate cell function is through an inducible kinase or phosphatase activity, including tyrosine kinase activity which is either endogenous to the receptor or is imparted by other proteins that become associated with the receptor. (Darnell et al., 1994, Science, 264:1415-1421; Heldin, 1995, Cell, 80:213-223; Pawson, 1995, Nature, 373:573-580). Protein tyrosine kinases (PTK) comprise a large family of transmembrane receptor and intracellular enzymes with multiple functional domains (Taylor et al., 1992, Ann. Rev. Cell Biol. 8:429-62). The binding of ligand allosterically transduces a signal across the cell membrane where, the cytoplasmic portion of the PTKs initiates a cascade of molecular interactions that disseminate the signal throughout the cell and into the nucleus. Many receptor protein tyrosine kinase (RTKs), such as epidermal growth factor receptor (EGFR) and platelet-derived growth factor receptor (PDGFR) undergo oligomerization upon ligand binding, and the receptors self-phosphorylate (via autophosphorylation or transphosphorylation) on specific tyrosine residues in the cytoplasmic portions of the receptor (Schlessinger and Ullrich, 1992, Neuron, 9:383-91, Heldin, 1995, Cell, 80:213223). Cytoplasmic protein tyrosine kinases (CTKs), such as Janus kinases (e.g., JAK1, JAK2, TYK2) and Src kinases (e.g., src, lck, fyn) are associated with receptors for cytokines (e.g., IL-2, IL-3, IL-6, erythropoietin), interferons and antigens. These associated receptors also undergo oligomerization, and have tyrosine residues that become phosphorylated during activation, but the receptor polypeptides themselves do not possess kinase activity.

[0007] Like the PTKS, the protein tyrosine phosphatases (PTPs) comprise a family of transmembrane and cytoplasmic enzymes, possessing at least an approximately 230 amino acid catalytic domain containing a highly conserved active site with the consensus motif [I/V]HCXXXXXR[S/T] (SEQ ID NO: 1). The substrates of PTPs may be PTKs which possess phosphotyrosine residues or the substrates of PTKs. (Hunter, 1989, Cell, 58:1013-16; Fischer et al., 1991, Science, 253:401-6; Saito and Streuli, 1991, Cell Growth and Differentiation, 2:59-65; Pot and Dixon, 1992, Biochem. Biophys. Acta, 1136:35-43).

[0008] Transmembrane or receptor-like PTPs (RTPs) possess an extracellular domain, a single transmembrane domain, and one or two catalytic domains followed by a short cytoplasmic tail. The extracellular domains of these RTPs are highly divergent, with small glycosylated segments (e.g., RTPα, RTPε), tandem repeats of immunoglobulin-like and/or fibronectin type III domains (e.g., LAR) or carbonic anhydrase like domains (e.g., RTPα, RTPβ). These extracellular features might suggest that these RTPs function as a receptor on the cell surface, and their enzymatic activity might be modulated by ligands. Intracellular or cytoplasmic PTPs (CTPs), such as PTP1C and PTP1D, typically contain a single catalytic domain flanked by several types of modular conserved domains. For example, PTP1C, a hemopoietic cell CTP, is characterized by two Src homology 2 (SH2) domains that recognize short peptide motifs bearing phosphotyrosine (pTyr).

[0009] In general, these modular conserved domains may influence the intracellular localization of the protein. SH2-domain containing proteins are able to bind pTyr sites in activated receptors and cytoplasmic phosphoproteins. Another conserved domain known as SH3 binds to proteins with proline-rich regions. A third type known as the pleckstrin-homology (PH) domain has also been identified. These modular domains have been found in both CTKs and CTPs as well as in noncatalytic adapter molecules, such as Grbs (Growth factor Receptor Bound), which mediate protein-protein interactions between components of the signal transduction pathway (Skolnik et al., 1991, Cell, 65:83-90; Pawson, 1995, Nature, 373:573-580).

[0010] Multiprotein signaling complexes comprising receptor subunits, kinases, phosphatases and adapter molecules are assembled in subcellular compartments through the specific and dynamic interactions between these domains and their binding motifs. Such signaling complexes integrate the extracellular signal with the ligand-bound receptor and relay the signal to other downstream signaling proteins or complexes in other locations inside the cell, including the nucleus (Koch et al., 1991, Science, 252:668-674; Pawson, 1994, Nature, 373:573-580; Mauro et al., 1994, Trends Biochem. Sci., 19:151-155; Cohen et al., 1995, Cell, 80:237-248).

[0011] The levels of phosphorylation required for normal cell growth and differentiation at any time are achieved through the coordinated action of phosphatases and kinases. Depending on the cellular context, these two types of enzymes may either antagonize or cooperate with each other during signal transduction. An imbalance between these enzymes may impair normal cell functions leading to metabolic disorders and cellular transformation.

[0012] For example, insulin binding to the insulin receptor, which is a PTK, triggers a variety of metabolic and growth promoting effects such as glucose transport, biosynthesis of glycogen and fats, DNA synthesis, cell division and differentiation. Diabetes mellitus, which is characterized by insufficient or a lack of insulin signal transduction, can be caused by any abnormality at any step along the insulin signaling pathway. (Olefsky, 1988, “Cecil Textbook of Medicine,” 18th Ed., 2:1360-81).

[0013] It is also well known, for example, that the overexpression of PTKS, such as HER2, can play a decisive role in the development of cancer (Slamon et al., 1987, Science, 235:77-82) and that antibodies capable of blocking the activity of this enzyme can abrogate tumor growth (Drebin et al., 1988, Oncogene, 2:387-394). Blocking the signal transduction capability of tyrosine kinases such as Flk-1 and the PDGF receptor have been shown to block tumor growth in animal models (Millauer et al., 1994, Nature, 367:577; Ueno et al., 1991, Science, 252:844-848).

[0014] Relatively less is known with respect to the direct role of tyrosine phosphatases in signal transduction. However, PTPs have been linked to human diseases. For example, ectopic expression of RTPα produces a transformed phenotype in embryonic fibroblasts (Zheng et al., 1992, Nature, 359:336-339), and overexpression of RTPα in embryonal carcinoma cells causes the cells to differentiate into a cell type with a neuronal phenotype (den Hertog, et al., 1993, EMBO Journal, 12:3789-3798). The gene for human RTPγ has been localized to chromosome 3p²¹ which is a segment frequently altered in renal and small lung carcinoma. Mutations may occur in the extracellular segment of RTPγ which renders the RTP no longer responsive to external signals (LaForgia et al., 1993, Cancer Res., 53:3118-3124; Wary et al., 1993, Cancer Res., 52:478-482). Mutations in the gene encoding PTP1C (also known as HCP or SHP) are the cause of the moth-eaten phenotype in mice which suffer from severe immunodeficiency, and systemic autoimmune disease accompanied by hyperproliferation of macrophages (Schultz et al., 1993, Cell, 73:1445-1454). PTP1D (also known as Syp, SHP2 or PTP2C) has been shown to bind through SH2 domains to sites of phosphorylation in PDGFR, EGFR and insulin receptor substrate 1 (IRS-1). Reducing the activity of PTP1D by microinjection of anti-PTP1D antibody has been shown to block insulin or EGF-induced mitogenesis (Xiao et al., 1994, J. Biol. Chem., 269:21244-21248).

[0015] It has been reported that some of the biological effects of insulin can be mimicked by vanadium salts such as vanadates and pervanadates. Vanadates and pervanadates are known to be non-specific phosphatase inhibitors. However, this class of compounds is toxic because each compound contains a heavy metal (U.S. Pat. No. 5,155,031; Fantus et al., 1989, Biochem., 28:8864-71; Swarup et al., 1982, Biochem. Biophys. Res. Commun., 107:1104-9). Others have reported non-peptidyl inhibitors of protein tyrosine phosphatase 1B.

[0016] Trifluoromethyl Sulfonyl Compounds

[0017] Trifluoromethyl sulfonyl compounds have been previously disclosed for uses unrelated to the present invention. For example, Pawloski et al., U.S. Pat. No. 5,480,568 disclose aryl triflouromethyl sulfonyl compounds for use as high temperature lubricants for magnetic recording media. Haug et al., U.S. Pat. No. 5,117,038 disclose triflouromethyl phenoxyphenylpropionic acid derivatives as herbicides. Others, namely Haga et al., U.S. Pat. No. 4,985,449 disclose trifluoromethyl sulfonyl phenoxy compounds for use as pesticides. Markley et al., U.S. Pat.

Examples of such compounds include Serban et al., EP 13144; Hartmann et al., U.S. Pat. No. 4,459,304 (insecticides, bactericides and fungicides). Still others have disclosed compounds with a single sulfur atom linker between the aromatic rings as synthetic intermediates to prepare trifluoromethyl sulfonyl substituted piperazinyl-benzothiazepines for use as sedatives, tranquilizers, antidepressants, and antiemetics (Schmutz et al., GB 1411587). Young et al., EP 233763, disclose sulfur linked quinolinyl trifluoromethyl sulfonyl compounds for use as a leukotriene antagonists.

[0018] Also, trifluoromethyl sulfonamido compounds have been previously disclosed for uses unrelated to the present invention. Hall et al., U.S. Pat.

Specifically, Fukada et al., WO 97/11050 and Toriyabe et at., 5,728,699, disclose methylene linked trifluoromethyl sulfonyl benzophenone and hydrazone as pesticides.

[0020] Although a great deal of information has been described about signal transduction and protein target associated therewith, there remains a need for drugs that effectively interact with these treat disease. Such drugs may be discovered from compounds published in the literature or novel compounds yet to be synthesized.

[0052] Treatment of Disease Using Phosphate Mimics

[0053] Based in part upon an investigation of the activity of the above compounds in both biochemical and cellular assays, we have discovered that compounds having a trifluoromethylsulfonyl moiety and its derivative trifluoromethylsulfonamido have a broad spectrum of activity. Presently, without being limited by any specific mechanism of action, such compounds mimic the effects of the phosphate group for a wide variety of phospho-derivatives including proteins such as phosphatases and kinases, e.g., phosphotyrosine, thus providing inhibition of a variety of important therapeutic targets. The compounds of the invention are stable to phosphatase, capable of crossing cell membranes and readily prepared in high purity. Thus, these compounds are uniquely suitable for use as medicaments.

[0054] The compounds and pharmaceutical compositions of the invention can be used for treating, alleviating or preventing diseases, including but not limited to, diabetes mellitus; immune disorders in which cytokine signal transduction is deficient specifically anemia and immunodeficiency; rheumatoid arthritis; neurodegenerative diseases; cancer, particularly solid tumors, such as glioma, melanoma, Kaposi's sarcoma, hemangioma and ovarian, breast, lung, pancreatic, liver, prostate, colon and epidermoid cancer, in which the malignant cells proliferate and/or metastasize as a result of uncontrolled signal transduction mediated by growth factors; infectious diseases associated with PTPases; or osteoporosis.

[0055] In addition, this invention provides a method for inhibiting, regulating or modulating the activity of a phosphate binding protein in a cell which comprises administering to the cell an effective amount of a compound with a molecular weight less than 2000 daltons, or a pharmaceutically acceptable salt or solvate thereof.

DETAILED DESCRIPTION OF THE INVENTION

[0064] Phosphatase Inhibition

[0065] The present invention encompasses compounds capable of acting as phosphate mimics, including but not limited to, inhibiting the activity of phosphatases and kinases. More specifically, the present invention encompasses compounds capable of inhibiting phosphatase activity. These compounds will be referred to herein generically as “phosphatase inhibitors”, even though these compounds either upregulate or downregulate cellular processes that are controlled by signal transduction. Without being limited by any specific mechanism of action, the small molecules of the invention have activity as phosphate mimics thus may achieve phosphatase inhibition in a cell.

[0066] The invention encompasses a method for regulating, inhibiting or modulating protein tyrosine phosphatase signal transduction in a mammalian cell comprising contacting the cell with an effective amount of administration to a mammal of a pharmaceutically effective amount of a compound as described above and a pharmaceutically acceptable carrier or excipient.

[0067] The present invention encompasses the use of compounds capable of modulating or regulating signal transduction in normal or diseased cells. The present invention is also directed to the use of compounds capable of inhibiting the activity of enzymes, in particular kinases and phosphatases, to modulate or trigger signal transduction. The invention is further directed to the regulation of cellular processes that are controlled by signal transduction through the inhibition of the activity of these enzymes by the compounds. The compounds of this invention are particularly suited for the prevention or treatment of cancer, diabetes, immunomodulation related disorders, neurologic degenerative disorders or osteoporosis. The invention further provides for the use of such compounds in the treatment of a subject having a disorder caused by dysfunctional signal transduction involving a kinase or a phosphatase.

[0068] In one embodiment of the invention, the compounds of the invention are capable of inhibiting the activity of protein tyrosine phosphatases, that are transmembrane or intracellular, and that may have one or more characteristic catalytic domains. The amino acid sequences of the PTPs in the catalytic domains may include but are not limited to [I/V]HCXXXXXR[S/T](SEQ ID NO: 1). In addition, the PTPs may possess one or more modular conserved domains, which include but are not limited to, SH2, SH3 and PH domains. In a specific embodiment of the invention, the compounds of the invention can be used to inhibit the phosphatase activity of PTP1B (Charbonneau, et al., 1989, Proc. Natl. Acad. Sci., USA, 86:5252-5256), T-cell PTP (Cool et al., 1989, Proc. Natl. Acad. Sci., USA, 86:5257-5261), PTP1C (Shen et al., 1991, Nature, 352:736-739), PTP1D (Vogel, et al., 1993, Science, 259:1611-1614), RTPα, RTPβ, RTPγ (Kaplan et al., 1990, Proc. Natl. Acad. Sci., USA, 87:7000-7004), RTPα (Yan, et al., 1993, J. Biol. Chem., 268: 24880-24886), RTPκ (Jiang et al., 1993, Mol. Cell Biol., 13:2942-2951) and CD45 (Charbonneau et al., 1988, Proc. Natl. Acad. Sci. USA, 85: 182-7186). The PTKs and PTPs preferred in the invention are of human origin. Inhibition of phosphatase activity that is substantially specific to a PTP or a set of PTPs in a signaling pathway is preferred. While the inhibition of phosphatase activity is believed to be a mechanism of action of the compounds of the present invention with respect to their ability to modulate and/or regulate signal transduction, applicants do not intend to be limited to a particular mechanism of action.

[0069] The term “signal transduction” as used herein is not limited to transmembrane signaling, and includes the multiple pathways that branch off throughout the cell and into the nucleus. Such signaling pathways may include but are not limited to the Ras pathway (Schlessinger, 1994, Curr. Opin. Genet. Dev., 4:25-30), the JAK/STAT pathways (Sadowski et al., 1994, Science, 261:1739-1744), the phosphoinositide 3-kinase pathway and the phospholipase C-γ pathway. As used herein, the term “modulation” or “modulating” shall mean upregulation or downregulation of a signaling pathway. Cellular processes under the control of signal transduction may include, but are not limited to, transcription of specific genes; normal cellular functions, such as metabolism, proliferation, differentiation, adhesion, apoptosis and survival; as well as abnormal processes, such as transformation, blocking of differentiation and metastasis.

[0070] A signal may be triggered by the binding of a ligand to its receptor on the cell surface, and the signal is transduced and propagated by the phosphorylation or dephosphorylation of specific tyrosine residues on various substrates inside the cell. The specific interactions between the kinases or phosphatases and their substrates may involve the formation of a transient or stable multimolecular complex on the inner face of the plasma membrane or in other subcellular compartments including the nucleus. A substrate may contain one or more residues that are phosphorylated or dephosphorylated by enzymes in the signaling pathway. Such substrates may include the receptor and its subunits, molecules associated with or recruited to the receptor such as cytoplasmic kinases, cytoplasmic phosphatases, adapter molecules, cytoskeletal proteins and transcription factors.

[0071] The term “receptor” as used herein may include, but is not limited to, insulin receptor, members of the insulin-like growth factor receptor family, epidermal growth factor receptor family, fibroblast growth factor receptor family, hepatocyte growth factor receptor family, vascular endothelial growth factor receptor family, neurotrophin receptor (trk) family, the T-cell receptor, the B cell receptor and members of the Type I-IV cytokine receptor families (Heldin, 1995, Cell, 80:213-223; Taniguchi, 1995, Science, 268:251-255). Adapter molecules that are substrates may include the Grb proteins, IRS-1, Zap-70 and Shc (Pawson et al., 1995, Nature, 373:573-580). Cytoskeletal proteins such as actin and transcription factors such as the STAT proteins (Ihle et al., 1994, Trends Biochem. Sci., 19:222-227) may also serve as substrates. As used herein, the term ligand is synonymous with extracellular signaling molecules, and includes but is not limited to growth factors such as insulin, EGF, PDGF, fibroblast growth factors, vascular endothelial growth factor, and neurotrophins; and cytokines such as growth hormone, erythropoietin, tumor necrosis factor, interleukins and interferons. The term ligand is not limited to soluble molecules, and includes, for example, extracellular matrix proteins, cell adhesion molecules as well as antigenic peptides associated with the major histocompatibility complex proteins on the surface of an antigen-presenting cell.

[0072] In one embodiment of the invention, the compounds of the invention can be used to trigger or upregulate signal transduction in cells so that the effect of ligand binding to a receptor is enhanced, or mimicked if the ligand is not present. The compounds exert the effect by inhibiting or diminishing the activity of a phosphatase in the signaling pathway which normally acts negatively toward signaling. One mechanism by which phosphatases normally downregulate signal transduction involves the dephosphorylation of specific phosphotyrosine residues (pTyr) on PTKs and their substrates since many PTKs require phosphorylation of some of its own tyrosine residues in order to become optimally active in the signaling pathway. The compounds of the invention can be used to prevent the dephosphorylation of pTyr residues on receptors or their subunits which normally becomes phosphorylated upon ligand binding, thereby enhancing the extent and duration of phosphorylation. The compounds of the invention can also be used to prevent the dephosphorylation of kinases in which the residues become autophosphorylated or transphosphorylated due to its basal activity. In these kinases, a signal may be triggered by the compounds of the invention in the absence of ligand binding since the basal activity of kinase is sufficient to promote a signal if constitutive phosphatase activity is inhibited or diminished by the compounds.

[0073] One embodiment of the invention is directed to a method of triggering, enhancing or sustaining insulin receptor signal transduction by inhibiting the constitutive dephosphorylation of sites on the activated insulin receptor. This would allow the insulin receptor to remain phosphorylated, thus enhancing or sustaining the insulin signal. Furthermore, since it has been shown that insulin receptor is phosphorylated at a low level even in the absence of insulin (Goldstein, 1992, J. Cell Biol., 48:33-42), the compounds of the invention can be used to trigger a signal, even in the absence of insulin, by allowing the tyrosine residues on the receptor to become self-phosphorylated.

[0074] Another mechanism by which phosphatases may exert a negative effect on signaling is through the dephosphorylation of specific sites to which SH2-containing molecules bind during signaling. The absence of such sites would prevent the recruitment of SH2-containing molecules to specific subcellular compartments to form multiprotein signaling complexes, thereby, preventing the further propagation of the signal. Thus, the compounds of the invention can be used to upregulate or prolong signal transduction by preventing the dephosphorylation of sites on substrate proteins that normally serve as binding sites for SH2-containing proteins which promote signaling. In another embodiment of the invention, the compounds of the invention may be used to prevent the dephosphorylation of specific residues on any substrate, which residues are essential to the transmissions or propagation of the signal. Furthermore, the compounds of the invention may be used to prevent the dephosphorylation of specific residues on any substrate, which residues are inhibitory to signal transduction.

[0075] The compounds of the invention can also be used to suppress or downregulate signal transduction in cells so that the effect of ligand binding to a receptor is abolished or attenuated. The compounds can inhibit a phosphatase in a signaling pathway which normally acts positively toward signaling. For example, phosphatases promote signaling through the activation of members of the Src family of kinases. Src family kinases have an inhibitory site of phosphorylation in their carboxy termini which by dephosphorylation activates kinase activity. Thus, the compounds of the invention can be used to prevent the dephosphorylation of the inhibitory residues in the carboxy termini of kinases which function normally to promote signal transductions. Src family kinases may include Src, Fyn, Lck, Lyn, Blk, Hck, Fgr and Yrk. Other kinases which may be similarly regulated by a phosphatase may include Fak and Csk (Taniguchi, 1995, Science, 268:251-255).

Nature 382 (1996) 555-559; Hoffmann et al. J. Biol. Chem. 272 (1997) 27505-27508; Hof et al. Cell 92 (1998) 441-450; Yuvaniyama et al. Science 272 (1996) 1328-1331; Fauman et al. Cell 93 (1998) 617-625; Su et al. Nature 370 (1994) 575-578; Zhang et al. Biochemistry 33 (1994) 11097-11105; Zhang et al. J. Mol. Biol. 238 (1994) 281-283; Zhang et al. J. Biol. Chem. 273 (1998) 21714-21720; Puius et al. Proc. Natl. Acad. Sci. USA 94 (1997) 13420-13425; Burke et al. Biochemistry 35 (1996) 15989-15996.) The signature motif CXXXXXR in these tyrosine phosphatases forms a remarkably similar phosphate binding site in the three-dimensional structure despite, in some cases, little or no sequence homology in the catalytic domain. Clearly, the conserved signature motif, which recognizes the phosphoryl group in a similar way, dictates the common catalytic mechanism of PTPs. In addition, the crystal structure of PTP1B complexed with a high affinity substrate (DADEpYL-NH2) revealed significant ligand-protein interactions occurring outside the catalytic site. (Jia, et al. Science 268 (1995) 1754-1758.) These interactions between the peptide and the surface (Y-loop) in PTPs may be important to the substrate specificity as well as potency. Another crystallographic study of PTP1B complexed with a small molecule BPPM identified a second aryl phosphate-binding site in PTP1B. (Puius et al. Proc. Natl. Acad. Sci. USA 94 (1997) 13420-13425.) This is a low-affinity, noncatalytic binding site adjacent to the active site. These results suggest that potent and selective PTP inhibitors could be developed by including these additional surface interactions.

[0265] In one method a design strategy may focus on the development of PTP inhibitors which contain not only a phosphate mimic but also components for additional interactions outside the active site for higher affinity and specificity. Using the techniques of computational chemistry including de novo design, pharmacophore development, and database search, several candidate PTP inhibitors were chosen for screening. Among them a trifluoromethylsulfonyl compound was determined as the initial lead. Subsequently, analogs of it were synthesized and many of these analogs showed good potency as well as selectivity. The most critical component in these compounds is the trifluoromethylsulfonyl moiety and its derivative trifluoromethylsulfonamido that mimic the effects of the phosphate group in phosphotyrosine. These moieties were used as phosphate mimics. Molecular modeling studies indicated that these phosphate mimics could effectively replicate the important hydrogen bonding interactions of the parent phosphate with PTPs. The noncharged nature of our phosphate mimics were of particular interest since most of the membrane permeability problems associated with known PTP inhibitors are from a charged phosphate mimic.

[0266] A direct comparison of our three compounds shown in the table below indicated that a change of the R group from CF₃SO₂NH— to CH₃SO₂NH— resulted in a dramatic decrease in activity, and, furthermore, a change from CF₃SO₂NH to NH₂ led to a complete loss of activity. These results provide a strong support to our hypothesis that the trifluoromethyl sulfonyl group is a phosphate mimic. IC₅₀ (μM) compound R = 1B SHP2 Epsilon MEG2 Sigma Beta Mu CF₃SO₂NH— 10.6 3.4 16.9 39.4 44 12.1 4 CH₃SO₂NH— 51.9 33.6 51.4 >100 22 62.6 >100 NH₂ >100 >100 >100 >100 >100 >100 >100

[0267] In addition to the phosphate mimic moiety, our analogs exemplified contain structural components expected to interact with either the surface Y-loop or the second pY binding site. These structural components were designed mainly based upon the known crystal structures. The molecular modeling studies used in the present invention have been performed using commercial software packages Sybyl (Tripos, Inc.) and Insight II (Molecular Simulations). The contents of each of these programs is hereby incorporated by reference into the subject application.

[0269] A “pharmaceutical composition” refers to a mixture of one or more of the compounds described herein, or physiologically acceptable salts, solvates, or prodrugs thereof, with other chemical components, such as physiologically acceptable carriers and excipients. The purpose of a pharmaceutical composition is to facilitate administration of a compound to an organism.

[0270] As used herein, “pharmaceutically acceptable salt” refers to those salts which retain the biological effectiveness and properties of the compound and which are obtained by reaction with acids or bases. Examples as such include but are not limited to ethanesulfonic acid, hydrobromic acid, hydrochloric acid, methanesulfonic acid, nitric acid, p-toluenesulfonic acid, phosphoric acid, salicylic acid, sulfuric acid, and the like. Others are known in the pharmaceutical arts.

[0271] As used herein, a “physiologically acceptable carrier” refers to a carrier or diluent that does not cause significant irritation to an organism and does not abrogate the biological activity and properties of the administered compound.

[0272] A “prodrug” refers to an agent which is converted into the parent drug or active form in vivo. Prodrugs are often useful because, in some situations, they may be easier to administer than the parent drug. They may, for instance, be bioavailable by oral administration whereas the parent drug is not. The prodrug may also have improved solubility in pharmaceutical compositions over the parent drug. An example, without limitation, of a prodrug would be a compound of the present invention wherein it is administered as an ester (the “prodrug”) to facilitate transmittal across a cell membrane where water solubility is not beneficial, but then it is metabolically hydrolyzed to the carboxylic acid once inside the cell where water solubility is beneficial. In addition, compounds of the present invention may be modified by the addition of one or more amino acids. Cleavage esters, such as phosphate esters, and amino acids are known in the art.

[0273] An “excipient” refers to an inert substance added to a pharmaceutical composition to further facilitate administration of a compound. Examples, without limitation, of excipients include calcium carbonate, calcium phosphate, various sugars and types of starch, cellulose derivatives, gelatin, vegetable oils and polyethylene glycols. Excipients well known in the art can be found, inter alia, in “Remington's Pharmaceutical Sciences”, Mack Publishing Co., Easton, Pa.

[0274] In addition to the above compounds and their pharmaceutically acceptable salts, the present invention is further directed, where applicable, to solvated as well as unsolvated forms of the compounds (e.g., hydrated forms) having the ability to regulate and/or modulate phosphatase activity.

Suitable processes are illustrated by the representative examples provided, infra. Necessary starting materials may be obtained commercially or prepared by standard procedures of organic chemistry.

[0276] The formulations of the present invention normally will consist of at least one compound of formula I, II or III mixed with a carrier, or diluted by a carrier, or enclosed or encapsulated by an ingestible carrier in the form of a capsule, sachet, cachet, paper or other container or by a disposable container such as an ampoule. A carrier or diluent may be a solid, semi-solid or liquid material, which serves as a vehicle, excipient or medium for the active therapeutic substance.

[0277] Some examples of the diluents or carriers which may be employed in the pharmaceutical compositions of the present invention are lactose, dextrose, sucrose, sorbitol, mannitol, propylene glycol, liquid paraffin, white soft paraffin, kaolin, microcrystalline cellulose, calcium silicate, silica polyvinylpyrrolidone, cetostearyl alcohol, starch, gum acacia, calcium phosphate, cocoa butter, oil of theobroma, arachis oil, alginates, tragacanth, gelatin, syrup B.P., methyl cellulose, polyoxyethylene sorbitan monolaurate, ethyl lactate and propylhydroxybenzoate, sorbitan trioleate, sorbitan sesquioleate and oleyl alcohol.

[0278] Routes of Administration

[0279] As used herein, “administer” or “administration” refers to the delivery of a compound, salt, solvate or prodrug of the present invention or of a pharmaceutical composition containing a compound, salt, solvate or prodrug of this invention to an organism for the purpose of prevention or treatment of a disorder associated a phosphate binding protein including an abnormal enzyme related cellular signal transduction.

[0280] As used herein, a “disorder associated with an abnormal enzyme related cellular signal transduction” refers to a condition characterized by inappropriate, i.e., under or, more commonly, over, catalytic activity on the part of an enzyme. Inappropriate catalytic activity can arise as the result of either: (1) enzyme expression in cells which normally do not express such enzymes; (2) increased enzyme expression leading to unwanted cell proliferation, differentiation and/or growth; or, (3) decreased enzyme expression leading to unwanted reductions in cell proliferation, differentiation and/or growth. Over-activity of enzymes includes amplification of the gene encoding a particular enzyme or production of a level of enzyme activity which can correlate with a cell proliferation, differentiation and/or growth disorder (that is, as the level of the enzyme increases, the severity of one or more of the symptoms of the cellular disorder increases). Underactivity is, of course, the converse, wherein the severity of one or more symptoms of a cellular disorder increase as the level of the enzyme decreases,

[0281] As used herein, the terms “inhibit”, “inhibiting” and “inhibition” of the activity of a phosphate binding protein refer to a method for reducing the activity either in an in vitro assay or in vivo system.

[0282] As used herein, the terms “modulate”, “modulating” and “modulation” of the activity of a phosphate binding protein refer to a method for altering the activity either in an in vitro assay or in vivo system. The activity may be reduced or increased depending on the particular system.

[0283] As used herein, the terms “prevent”, “preventing” and “prevention” refer to a method for barring an organism from in the first place acquiring a disorder associated with phosphate binding protein activity including kinase or phosphatase activity which may be related to cellular signal transduction.

[0284] As used herein, the terms “regulate”, “regulating” and “regulation” of activity of a phosphate binding protein refer to a method for controlling the phosphate binding activity either in an in vitro assay or in vivo system. The term includes upregulation and downregulation.

[0285] As used herein, the terms “treat”, “treating” and “treatment” refer to a method of alleviating or abrogating a disease and/or its attendant symptoms to provide a therapeutic benefit including those associated with a phosphate binding protein including an abnormal enzyme related cellular signal transduction disorder. With regard particularly to cancer, these terms simply mean that the life expectancy of an individual affected with a cancer will be increased or that one or more of the symptoms of the disease will be reduced.

[0286] The term “organism” refers to any living entity comprised of at least one cell. A living organism can be as simple as, for example, a single eukaryotic cell or as complex as a mammal, including a human being.

[0287] (Suitable routes of administration include, without limitation, oral, rectal, intransal, transmucosal, or intestinal administration; parentheral including but not limited to, intramuscular, subcutaneous, intramedullary, intrathecal, direct intraventricular, intravenous, intraperitoneal, or intraocular injections; transdermal, topical and vaginal application, and the like. Dosage forms include but are not limited to tablets, troches, dispersions, suspensions, lyophilized powders or solids suitable for reconstitution, suppositories, solutions, capsules, creams, patches, lotions, minipumps and the like.

[0288] Alternately, one may administer the compound in a local rather than systemic manner, for example, via injection (e.g., bolus injection) of the compound directly into a solid tumor, often in a depot or sustained release formulation.

[0289] Furthermore, one may administer the drug in a targeted drug delivery system, for example, in a liposome coated with tumor-specific antibody. The liposomes will be targeted to and taken up selectively by the tumor.

[0290] Composition/Formulation

[0291] The pharmaceutical compositions of the present invention may be manufactured by processes well known in the art, for example and without limitation by means of conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping or lyophilizing processes.

[0292] Pharmaceutical compositions for use in accordance with the present invention thus may be formulated in conventional manner using one or more physiologically acceptable carriers comprising excipients and auxiliaries which facilitate processing of the active compounds into preparations which can be used pharmaceutically. Proper formulation is dependent upon the route of administration chosen.

[0293] For injection, the agents of the invention maybe formulated in aqueous solutions, preferably in physiologically compatible buffers such as Hanks's solution, Ringer's solution, or physiological saline buffer. For transmucosal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants are generally known in the art.

[0294] For oral administration, the compounds can be formulated readily by combining the active compounds with pharmaceutically acceptable carriers well known in the art. Such carriers enable the compounds of the invention to be formulated as tablets, pills, dragees, capsules, liquids, gels, syrups, slurries, suspensions and the like, for oral ingestion by a patient to be treated. Pharmaceutical preparations for oral use can, for instance, be prepared by adding a compound of this invention to a solid excipient, optionally grinding the resulting mixture and processing the mixture of granules, after adding suitable auxiliaries, if desired, to obtain tablets or dragee cores. Suitable excipients are, in particular, fillers such as sugars, including lactose, sucrose, mannitol, or sorbitol; cellulose preparations such as, for example, maize starch, wheat starch, rice starch, potato starch, gelatin, gum tragacanth, methyl cellulose, hydroxypropylmethyl-cellulose, sodium carboxymethylcellulose, and/or polyvinylpyrrolidone (PVP). If desired, disintegrating agents may be added, such as the cross-linked polyvinyl pyrrolidone, agar, or alginic acid or a salt thereof such as sodium alginate.

[0295] Dragee cores are provided with suitable coatings. For this purpose, concentrated sugar solutions may be used, which may optionally contain gum arabic, talc, polyvinyl pyrrolidone, carbopol gel, polyethylene glycol, and/or titanium dioxide, lacquer solutions, and suitable organic solvents or solvent mixtures. Dyestuffs or pigments may be added to the tablets or dragee coatings for identification or to characterize different combinations of active compound doses.

[0296] Pharmaceutical preparations which can be used orally include push-fit capsules made of gelatin, as well as soft, sealed capsules made of gelatin and a plasticizer, such as glycerol or sorbitol. The push-fit capsules can contain the active ingredients in admixture with filler such as lactose, binders such as starches, and/or lubricants such as talc or magnesium stearate and, optionally, stabilizers. In soft capsules, the active compounds may be dissolved or suspended in suitable liquids, such as fatty oils, liquid paraffin, or liquid polyethylene glycols. In addition, stabilizers may be added. All formulations for oral administration should be in dosages suitable for such administration.

[0297] For buccal administration, the compositions may take the form of tablets or lozenges formulated in conventional manner. For administration by inhalation, the compounds for use according to the present invention are conveniently delivered in the form of an aerosol spray presentation from pressurized packs or a nebulizer, with the use of a suitable propellant, e.g., dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide or other suitable gas. In the case of a pressurized aerosol the dosage unit may be determined by providing a valve to deliver a metered amount. Capsules and cartridges of, e.g., gelatin for use in an inhaler or insufflator may be formulated containing a powder mix of the compound and a suitable powder base such as lactose or starch.

[0298] The compounds of this invention may be formulated for parenteral administration by injection, e.g., by bolus injection or continuous intravenous infusion. Formulations for injection may be presented in unit dosage form, e.g., in ampoules or in multidose containers, with an added preservative. The compositions may take such forms as suspensions, solutions or emulsions in oily or aqueous vehicles, and may contain formulatory agents such as suspending, stabilizing and/or dispersing agents.

[0299] Pharmaceutical formulations for parenteral administration include aqueous solutions of the active compounds in water-soluble form. Additionally, suspensions of the active compounds may be prepared as appropriate oily injection suspensions. Suitable lipophilic solvents or vehicles include fatty oils such as sesame oil, or synthetic fatty acid esters, such as ethyl oleate or triglycerides, or liposomes. Aqueous injection suspensions may contain substances which increase the viscosity of the suspension, such as sodium carboxymethyl cellulose, sorbitol, or dextran. Optionally, the suspension may also contain suitable stabilizers or agents which increase the solubility of the compounds to allow for the preparation of highly concentrated solutions.

[0300] Alternatively, the active ingredient may be in powder form for constitution with a suitable vehicle, e.g., sterile pyrogen-free water, before use.

[0301] The compounds may also be formulated in rectal compositions such as suppositories or retention enemas, e.g., containing conventional suppository bases such as cocoa butter or other glycerides.

[0302] In addition to the formulations described previously, the compounds may also be formulated as a depot preparation. Such long acting formulations may be administered by implantation (for example subcutaneously or intramuscularly) or by intramuscular injection. Thus, for example, the compounds may be formulated with suitable polymeric or hydrophobic materials (for example as an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble derivatives such as, for example, a sparingly soluble salt.

[0303] A pharmaceutical carrier for the hydrophobic compounds may be a cosolvent system comprising benzyl alcohol, a nonpolar surfactant, a water-miscible organic polymer, and an aqueous phase. The cosolvent system may be the VPD co-solvent system. VPD is a solution of 3% w/v benzyl alcohol, 8% w/v of the nonpolar surfactant polysorbate 80, and 65% w/v polyethylene glycol 300, made up to volume in absolute ethanol. The VPD co-solvent system (VPD:0.5 W) consists of VPD diluted 1:1 with a 5% dextrose in water solution. This co-solvent system dissolves hydrophobic compounds well, and itself produces low toxicity upon systemic administration. Naturally, the proportions of a co-solvent system may be varied considerably without destroying its solubility and toxicity characteristics. Furthermore, the identity of the co-solvent components may be varied, for example, other low toxicity nonpolar surfactants may be used instead of polysorbate 80; the fraction size of polyethylene glycol may be varied; other biocompatible polymers may replace polyethylene glycol, e.g., polyvinyl pyrrolidone; and other sugars or polysaccharides may substitute for dextrose.

[0304] Alternatively, other delivery systems for hydrophobic pharmaceutical compounds may be employed. Liposomes and emulsions are well known examples of delivery vehicles or carriers for hydrophobic drugs. Certain organic solvents such as dimethylsulfoxide also may be employed, although usually at the cost of greater toxicity. Additionally, the compounds may be delivered using a sustained-release system, such as semipermeable matrices of solid hydrophobic polymers containing the therapeutic agent. Numerous sustained release products are well known by those skilled in the art. Sustained-release capsules may, depending on their chemical nature, release the compounds for a few weeks up to over 100 days. Depending on the chemical nature and the biological stability of the therapeutic reagent, additional strategies for protein stabilization may be employed.

[0305] The pharmaceutical compositions also may comprise suitable solid or gel phase carriers or excipients. Examples of such carriers or excipients include but are not limited to calcium carbonate, calcium phosphate, various sugars, starches, cellulose derivatives, gelatin, and polymers such as polyethylene glycols.

[0306] In addition to the common dosage forms set out above, the compounds of the present invention may also be administered by controlled release means and/or delivery devices including Alzet_osmotic pumps which are available from Alza Corporation. Suitable delivery devices are described in U.S. Pat. Nos. 3,845,770; 3,916,899; 3,536,809; 3,598,123; 3,944,064 and 4,008,719, the disclosures of which are incorporated in their entirety by reference herein.

[0307] Many of the phosphatase modulating compounds of the invention may be provided as salts with pharmaceutically compatible counterions. As previously discussed, pharmaceutically compatible salts may be formed with many acids, including but not limited to hydrochloric, sulfuric, acetic, lactic, tartaric, malic, succinic, etc. Salts tend to be more soluble in aqueous or other protonic solvents than are the corresponding free base forms.

[0308] Dosage

[0309] Pharmaceutical compositions suitable for use in the present invention include compositions wherein the active ingredients are contained in an amount effective to achieve its intended purpose. The term “therapeutically effective amount” as used herein refers to that amount of the compound being administered which will relieve to some extent one or more of the symptoms of the disorder being treated. In reference to the treatment of cancer, a therapeutically effective amount refers to that amount which has the effect of (1) reducing the size of the tumor; (2) inhibiting (that is, slowing to some extent, preferably stopping) tumor metastasis; (3) inhibiting to some extent (that is slowing to some extent, preferably stopping) tumor growth; and/or, (4) relieving to some extent (or preferably eliminating) one or more symptoms associated with the cancer. Determination of the therapeutically effective amount of a compound of this invention is well within the capability of those skilled in the art, especially in light of the detailed disclosure provided herein.

[0310] The therapeutically effective dose can be estimated initially from cell culture assays. For example, a dose can be formulated in animal models to achieve a circulating concentration range that includes the IC₅₀ as determined in cell culture (i.e., the concentration of the test compound which achieves a half-maximal inhibition of the enzyme activity). Such information can be used to more accurately determine useful doses in humans or in other subjects.

[0311] Thus, a therapeutically effective dose refers to that amount of the compound that results in amelioration of symptoms in or a prolonged survival of a patient. Toxicity and therapeutic efficacy of such compounds can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, e.g., for determining the LD50 (the dose lethal to 50% of the population) and the ED50 (the dose therapeutically effective in 50% of the population). The ratio of toxic does to therapeutic effective, e.g., LD50/ED50, is the therapeutic index. Compounds which exhibit high therapeutic indices are preferred. The data obtained from cell culture assays and animal studies can be used in formulating a range of dosages for use in humans. A dosage preferably lies within a range of circulating concentrations that include the ED5O and exhibits little or no toxicity. The dosage may vary within this range depending upon the dosage form employed and the route of administration utilized. The exact formulation, route of administration and dosage can be chosen by the individual physician in view of the patient's condition. (See e.g., Fingl et al., 1975, in “The Pharmacological Basis of Therapeutics”, Ch. 1, p.1), hereby incorporated by reference.

[0312] Dosage amount and interval may be adjusted individually to provide plasma levels of the active moiety which are sufficient to maintain the enzyme modulating effects, known as the minimal effective concentration (MEC). The MEC will vary for each compound but can be estimated from in vitro data; for example, without limitation, the concentration necessary to achieve a 50-90% inhibition of the tyrosine enzyme using the assays described herein. Dosages necessary to achieve the MEC will depend on individual characteristics and route of administration. HPLC assays or bioassays can be used to determine plasma concentrations.

[0313] Dosage intervals can also be determined using the MEC value. Compounds should be administered using a regimen which maintains plasma levels above the MEC for 10-90%, preferably between 30-90% and most preferably between 50-90% of the time.

[0314] Usual patient dosages for systemic administration of the therapeutics range from 1 to 2000 mg/day, commonly from 1 to 250 mg/day, and typically from 10 to 150 mg/day. Stated in terms of patient body weight, usual dosages range from 0.02 to 25 mg/kg/day, commonly from 0.02 to 3 mg/kg/day, typically from 0.2 to 1.5 mg/kg/day. Stated in terms of patient body surface areas, usual dosages range from 0.5 to 1200 mg/m²/day, commonly from 0.5 to 150 mg/m²/day, typically from 5 to 100 mg/m²/day. Usual average plasma levels should be maintained within 50 to 5000 μg/ml, commonly 50 to 1000 μg/ml, and typically 100 to 500 μg/ml.

[0315] In cases of local administration or selective uptake, the effective local concentration of the drug may not be related to plasma concentration.

[0316] The amount of a particular composition administered will, of course, be dependent on the subject being treated, on the subject's weight, the severity of the affliction, the manner of administration and the judgment of the prescribing physician.

[0317] Desirable blood levels may be maintained by a continuous infusion of the compound; plasma level can be monitored by HPLC. It should be noted that the attending physician would know how and when to terminate, interrupt or adjust therapy to lower dosage due to toxicity, or bone marrow, liver or kidney dysfunctions. Conversely, the attending physician would also know to adjust treatment to higher levels if the clinical response is not adequate and toxicity is not a problem.

[0318] The size of a prophylactic or therapeutic dose of a compound in the acute or chronic management of disease will vary with the severity of the condition to be treated and the route of administration. Again, it should be noted that the clinician or physician would know when to interrupt and/or adjust the treatment dose due to toxicity or bone marrow, liver or kidney dysfunctions. The dose, and perhaps the dosage frequency, will also vary according to the age, body weight, and response of the individual patient. In general, as discussed above, the total daily dose ranges for the compounds of the invention for the majority of the disorders described herein, is from about 0.02 to about 25 mg/kg patient. Preferably, a daily dose range should be between about 0.02 to about 3 mg/kg, while most preferably a daily dose range should be between about 0.2 to about 1.5 mg/kg per day. It is further recommended that infants, children, and patients over 65 years, and those with impaired renal, or hepatic function, initially receive low doses and that they be titrated based on individual clinical response(s) and blood level(s). It may be necessary to use dosages outside the above ranges in some cases; situations requiring such a decision will be apparent to those of ordinary skill in the art.

[0319] Packaging

[0320] The compositions may, if desired, be presented in a pack or dispenser device, such as an FDA approved kit, which may contain one or more unit dosage forms containing the active ingredient. The pack may for example comprise metal or plastic foil, such as a blister pack. The pack or dispenser device may be accompanied by instructions for administration. The pack or dispenser may also be accompanied by a notice associated with the container in a form prescribed by a governmental agency regulating the manufacture, use or sale of pharmaceuticals, which notice is reflective of approval by the agency of the form of the compositions or human or veterinary administration. Such notice, for example, may be of the labeling approved by the U.S. Food and Drug Administration (“FDA”) for prescription drugs or of an approved product insert. Compositions comprising a compound of the invention formulated in a compatible pharmaceutical carrier may also be prepared, placed in an appropriate container, and labeled for treatment of an indicated condition. Suitable conditions indicated on the label may include treatment of a tumor, inhibition of angiogenesis, treatment of fibrosis, diabetes, and the like.

[0443] In addition, the invention is directed to a method for treating a disease in a mammal associated with a phosphate binding protein which comprises administering to a mammal in need thereof a therapeutically effective amount of a compound with a molecular weight less than 2000 daltons, or a pharmaceutically acceptable salt or solvate thereof, wherein the compound contains at least one functional group selected from the group consisting of C(R¹¹)F_(a)SO_(b)Z-, and R¹²SO_(b)C(R¹¹)F_(m)—. In this embodiment, a is 1, 2 or 3 and b is 1 or 2 and m is 1 or 2; Z is C or N; R¹¹ may be present or absent and if present is independently H, halo, C1-C4 alkyl, C₂-C₄ alkenyl or C1-C4 haloalkyl, which may be substituted or unsubstituted; R¹² is C1-C3 haloalkyl, C1-C3 alkyl which may be substituted or unsubstituted, or N which may be substituted or unsubstituted; and a pharmaceutically acceptable carrier or excipient. Here, the compound treats the disease associated with the phosphate binding protein in the mammal.

[0444] Specifically, the phosphate binding protein is associated with cancer, a solid tumor, glioma, melanoma, Kaposi's sarcoma, hemangioma, ovarian cancer, breast cancer, lung cancer, pancreatic cancer, liver cancer, prostate cancer, colon cancer, or epidermoid cancer. In addition, the phosphate binding protein is associated with diabetes, neurological degenerative diseases, osteoporosis or a lymphatic function. Preferably, the phosphate binding protein is associated with lymphatic function is CD45. In addition, preferably the mammal is a human.

[0445] The phosphate mimic compounds disclosed herein may be used to treat and/or prevent cancer. Additional specific embodiments of the general method of treatment utilizing fluoro sulfonyl compounds may be found in the uses section above.

[0446] A compound of this invention can be administered to a veterinary or a human patient as such or in pharmaceutical compositions in which a therapeutically effective dose is mixed with suitable carriers or excipient(s) at doses to treat or ameliorate a variety of disorders, including solid cell tumor growth, including Kaposi's sarcoma, glioblastoma, and melanoma and ovarian, lung mammary, prostate, pancreatic, colon and epidermoid carcinoma, diabetes, diabetic retinopathy, hemangioma and rheumatoid arthritis. A therapeutically effective dose further refers to that amount of the compound sufficient to result in amelioration of symptoms of uncontrolled vasculogenesis and angiogenesis. Techniques for formulation and administration of the compounds such as those of this invention may be found in “Remington's Pharmaceutical Sciences,” Mack Publishing Co., Easton, Pa., latest edition.

[0447] The compounds and pharmaceutical compositions of the invention can be used for treating, preventing or controlling diabetes mellitus (including NIDDM, diabetes type I and II). The pathogenesis of diabetes generally involves insufficient or a total lack of insulin signal transduction. The paucity or absence of the insulin signal may be caused by a variety of factors such as a lack of insulin, loss of binding affinity, defective receptor or under expression of receptor. Insulin receptor activity can be modulated by inhibiting tyrosine phosphatases in the signaling using the compounds of the invention. Unlike currently available treatment modalities that are based on the insulin receptor, the insulin signal may be restored or stimulated in cells through the inhibition of dephosphorylating activity, even in the absence of insulin. The example of diabetes mellitus illustrates the principles of therapeutic applications of the compounds of this invention which may be applied to other disorders that implicate signal transduction by tyrosine enzymes, in particular, phosphotyrosine phosphatases.

[0448] The compounds and pharmaceutical compositions of the invention may be used to treat immune disorders in which cytokine signal transduction is deficient. Cytokines play a crucial role in hemopoiesis as well as coordinating immune and inflammatory responses. The compounds may be used to replace or enhance the activity of a cytokine in signaling the differentiation and proliferation of hemopoietic cells, as well as B and T cells in response to antigenic stimulation, and thus be useful for treating or preventing anemia and immunodeficiency.

[0449] The compounds may also be used as an antiinflammatory agent in treating or preventing disorders such as rheumatoid arthritis.

[0450] The compounds may also be therapeutically useful in treating or preventing neurodegenerative diseases by stimulating the growth and differentiation of neuronal cells which is regulated by neurotrophin-mediated signal transduction.

[0451] The compounds of this invention are useful for treating, alleviating or preventing neurologic degenerative diseases., A wide variety of PTPs are expressed in the nervous system and there are more studies showing that RTPs play a role in growth cone guidance, neuronal survival, cell fate determination and connectivity (Chien, 1996, Neuron, 16(6):1065-1068).

[0452] In addition the invention is directed to a method for treating, alleviating or preventing cancer in a human which comprises administering to a human in need thereof pharmaceutically effective amount of pharmaceutical composition comprising a compound of Formula (I), (II) or (III) as defined above. Specifically, the compounds and pharmaceutical compositions of the invention are useful for a variety of different cancers, particularly solid tumors, such as glioma, melanoma, Kaposi's sarcoma, hemangioma and ovarian, breast, lung, pancreatic, liver, prostate, colon and epidermoid cancer, in which the malignant cells proliferate and/or metastasize as a result of uncontrolled signal transduction mediated by growth factors. For example, over expression of a PTK, such as HER2 has been shown to correlate with the aberrant growth characteristics of tumor cells. Vasculogenesis and/or angiogenesis that facilitates tumor growth may also be inhibited by the compounds of this invention. The compounds may modulate signal transduction in these tumor cells so that normal growth characteristics are restored. The compounds may also be useful in treating psoriasis which is caused by excessive epidermal growth factor mediated signal transduction.

[0453] The compounds of this invention are useful for treating, alleviating or preventing Von Hippel Lindau Syndrome. (Maher et al., 1997, Medicine, 76(6):381-391).

[0454] The compounds of this invention are useful for immuno-modulation. The overexpression of some protein-tyrosine phosphatases may result in the expression of a transformed phenotype. The human gene encoding the hematopoeitic specific cytoplasmic protein tyrosine phosphatase, HePTP, was shown to be amplified and overexpressed in some myeloid malignancies and might contribute to abnormal myeloid cell growth (Zanke et al., 1994, Leukemia 8:236). Also CD45 has being shown to be required for T and B lymphocyte activation via their antigen receptors (Chan et al., 1994, Annu. Rev. Immunol. 12:555-592). Inhibition of CD45 could lead to immunosuppression.

[0455] The compounds of this invention are useful for treating, alleviating or preventing infectious diseases associated with PTPases. Thus, PTPase modulators may represent novel targets for antibiotic development. For instance Yersinia encodes a PTPase essential for its virulence. The genus Yersinia comprises three species of bacteria that are causative agents in human diseases ranging from gastrointestinal syndromes to the Bubonic Plague (Bolin and Wolf-Watz, 1988, Mol. Microbiol. 2(2):237)

[0456] The compounds of this invention may be useful for treating, alleviating or preventing osteoporosis. Bone remodeling requires regulated tyrosine phosphorylation mediated by specific protein tyrosine kinases and tyrosine phosphatases. Inhibition of PTPs would interfere with osteoclast resorption, resulting in reduced bone turnover and a net gain in bone mineral density (Rodan and Fleish, 1996, J.Clin.Invest. 97:2692-2696).

[0604] Compound Evaluation

[0605] It will be appreciated that, in any given series of compounds, a spectrum of biological activity will be observed. In one preferred embodiment, the present invention relates to trifluoromethyl sulfonyl and trifluoromethyl sulfonamido compounds demonstrating the ability to modulate phosphate binding proteins including enzymes related to cellular signal transduction, such as, protein tyrosine phosphatases. The assays described below are employed to select those compounds demonstrating the optimal degree of the desired activity.

[0606] As used herein, the phrase “optimal degree of desired activity” refers to the highest therapeutic index, defined above, against a phosphate binding protein including enzymes which mediates cellular signal transduction and which is related to a particular disorder so as to provide an animal or a human patient, suffering from such disorder with a therapeutically effective amount of a compound of this invention at the lowest possible dosage.

[0607] Assays For Determining Inhibitory Activity

[0608] Various procedures known in the art may be used for identifying, evaluating or assaying the inhibition of activity of phosphate binding proteins, including protein tyrosine phosphatases, by the compounds of the invention. For example but without limitation, with regard to phosphatases such assays involve exposing target cells in culture to the compounds and a) biochemically analyzing cell lysates to assess the level and/or identity of tyrosine phosphorylated proteins; or (b) scoring phenotypic or functional changes in treated cells as compared to control cells that were not exposed to the test substance.

[0609] Where mimics of the natural ligand for a signal transducing receptor are to be identified or evaluated, the cells are exposed to the compound of the invention and compared to positive controls which are exposed only to the natural ligand, and to negative controls which were not exposed to either the compound or the natural ligand. For receptors that are known to be phosphorylated at a basal level in the absence of the natural ligand, such as the insulin receptor, the assay may be carried out in the absence of the ligand. Where inhibitors or enhancers of ligand induced signal transduction are to be identified or evaluated, the cells are exposed to the compound of the invention in the presence of the natural ligand and compared to controls which are not exposed to the compound of the invention.

[0610] The assays described below may be used as a primary screen to evaluate the ability of the compounds of this invention to inhibit phosphatase activity of the compounds of the invention. The assays may also be used to assess the relative potency of a compound by testing a range of concentrations, in a range from 100 μM to 1 pM, for example, and computing the concentration at which the amount of phosphorylation or signal transduction is reduced or increased by 50% (IC₅₀) compared to controls.

[0611] Biochemical Assays

[0612] In one embodiment target cells having a substrate molecule that is phosphorylated or dephosphorylated on a tyrosine residue during signal transduction are exposed to the compounds of the invention and radiolabelled phosphate, and thereafter, lysed to release cellular contents, including the substrate of interest. The substrate may be analyzed by separating the protein components of the cell lysate using a sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) technique, in either one or two dimensions, and detecting the presence of phosphorylated proteins by exposing to X-ray film. In a similar technique, but without radioactive labeling, the protein components separated by SDS-PAGE are transferred to a nitrocellulose membrane, the presence of pTyr is detected using an antiphosphotyrosine (anti-pTyr) antibody. Alternatively, it is preferred that the substrate of interest be first isolated by incubating the cell lysate with a substrate-specific anchoring antibody bound to a solid support, and thereafter, washing away non-bound cellular components, and assessing the presence or absence of pTyr on the solid support by an anti-pTyr antibody. This preferred method can readily be performed in a microtiter plate format by an automated robotic system, allowing for testing of large numbers of samples within a reasonably short time frame.

[0613] The anti-pTyr antibody can be detected by labeling it with a radioactive substance which facilitates its detection by autoradiography. Alternatively, the anti-pTyr antibody can be conjugated with an enzyme, such as horseradish peroxidase, and detected by subsequent addition of an appropriate substrate for the enzyme, the choice of which would be clear to one skilled in the art. A further alternative involves detecting the anti-pTyr antibody by reacting with a second antibody which recognizes the anti-pTyr antibody, this second antibody being labelled with either a radioactive substance or an enzyme as previously described. Any other methods for the detection of an antibody known in the art may be used.

[0614] The above methods may also be used in a cell-free system wherein cell lysate containing the signal-transducing substrate molecule and phosphatase is mixed with a compound of the invention and a kinase. The substrate is phosphorylated by initiating the kinase reaction by the addition of adenosine triphosphate (ATP). To assess the activity of the compound, the reaction mixture may be analyzed by the SDS-PAGE technique or it may be added to a substrate-specific anchoring antibody bound to a solid support, and a detection procedure as described above is performed on the separated or captured substrate to assess the presence or absence of pTyr. The results are compared to those obtained with reaction mixtures to which the compound is not added. The cell-free system does not require the natural ligand or knowledge of its identity. For example, Posner et al. (U.S. Pat. No. 5,155,031) describes the use of insulin receptor as a substrate and rat adipocytes as target cells to demonstrate the ability of pervanadate to inhibit PTP activity. Burke et al., 1994, Biochem. Biophys. Res. Comm., 204:129-134) describes the use of autophosphorylated insulin receptor and recombinant PTP1B in assessing the inhibitory activity of a phosphotyrosyl mimetic.

[0615] In addition to measuring phosphorylation or dephosphorylation of substrate proteins, activation or modulation of second messenger production, changes in cellular ion levels, association, dissociation or translocation of signaling molecules, gene induction or transcription or translation of specific genes may also be monitored. These biochemical assays may be performed using conventional techniques developed for these purposes.

[0616] Biological Assays

[0617] The ability of the compounds of this invention to modulate the activity of PTPs, which control signal transduction, may also be measured by scoring for morphological or functional changes associated with ligand binding. Any qualitative or quantitative techniques known in the art may be applied for observing and measuring cellular processes which come under the control of phosphatases in a signaling pathway. Such cellular processes may include, but are not limited to, anabolic and catabolic processes, cell proliferation, cell differentiation, cell adhesion, cell migration and cell death.

[0618] The techniques that have been used for investigating the various biological effects of vanadate as a phosphatase inhibitor may be adapted for use with the compounds of the invention. For example, vanadate has been shown to activate an insulin-sensitive facilitated transport system for glucose and glucose analogs in rat adipocytes (Dubyak et al., 1980, J. Biol. Chem., 256:5306-5312). The activity of the compounds of the invention may be assessed by measuring the increase in the rate of transport of glucose analog such as 2-deoxy-3H-glucose in rat adipocytes that have been exposed to the compounds. Vanadate also mimics the effect of insulin on glucose oxidation in rat adipocytes (Shechter et al., 1980, Nature, 284:556-558). The compounds of this invention may be tested for stimulation of glucose oxidation by measuring the conversion of 14C-glucose to 14CO2. Moreover, the effect of sodium orthovanadate on erythropoietin-mediated cell proliferation has been measured by cell cycle analysis based on DNA content as estimated by incorporation of tritiated thymidine during DNA synthesis (Spivak et al., 1992, Exp. Hematol., 20:500-504). Likewise, the activity of the compounds of this invention toward phosphatases that play a role in cell proliferation may be assessed by cell cycle analysis.

[0619] The activity of the compounds of this invention can also be assessed in animals using experimental models of disorders caused by or related to dysfunctional signal transduction. For example, the activity of a compound of this invention may be tested for its effect on insulin receptor signal transduction in non-obese diabetic mice (Lund et al., 1990, Nature, 345:727-729), B B Wistar rats and streptozotocin-induced diabetic rats (Solomon et al., 1989, Am. J. Med. Sci., 297:372-376). The; activity of the compounds may also be assessed in animal carcinogenesis experiments since phosphatases can play an important role in dysfunctional signal transduction leading to cellular transformation. For example, okadaic acid, a phosphatase inhibitor, has been shown to promote tumor formation on mouse skin (Suganuma et al., 1988, Proc. Natl. Acad. Sci., 85:1768-1771).

[0620] The data obtained from these cell culture assays and animal studies can be used in formulating a range of dosages for use in humans. The dosage of the compounds of the invention should lie within a range of circulating concentrations with little or no toxicity. The dosage may vary within this range depending on the dosage form employed and the route of administration.

[0621] Phosphotyrosine Enzyme Linked Immunosorbent Assay

[0622] This assay may be used to test the ability of the compounds of the invention to inhibit dephosphorylation of phosphotyrosine (ptyr) residues on insulin receptor (IR). Those skilled in the art will recognize that other substrate molecules, such as platelet derived growth factor receptor, may be used in the assay by using a different target cell and anchoring antibody. By using different substrate molecules in the assay, the activities of the compounds of this invention toward different protein tyrosine enzymes may be assessed. In the case of IR, an endogenous kinase activity is active at low level even in the absence of insulin binding. Thus, no insulin is needed to stimulate phosphorylation of IR. That is, after exposure to a compound, cell lysates can be prepared and added to microtiter plates coated with anti-insulin receptor antibody. The level of phosphorylation of the captured insulin receptor is detected using an anti-pTyr antibody and an enzyme-linked secondary antibody.

[0623] Assay Methods in Determination of Compound-PTP IC₅₀

[0624] The following in vitro assay procedure is preferred to determine the level of activity and effect of the different compounds of the present invention on one or more of the PTPs. Similar assays can be designed along the same lines for any PTP using techniques well known in the art.

[0625] The catalytic assays described herein are performed in a 96-well format. The general procedure begins with the determination of PTP optimal pH using a three-component buffer system that minimizes ionic strength variations across a wide range of buffer pH. Next, the Michaelis-Menten constant, or Km, is determined for each specific substrate-PTP system. This Km value is subsequently used as the substrate reaction concentration for compound screening. Finally, the test PTP is exposed to varying concentrations of compound for fifteen minutes and allowed to react with substrate for ten minutes. The results are plotted as percent inhibition versus compound concentration and the IC₅₀ interpolated from the plot.

[0626] The following materials and reagents were used:

[0627] 1. Assay Buffer was Used as Solvent for all Assay Solutions Unless Otherwise Indicated. Component Concentration Acetate (Fisher Scientific A38-500) 100 mM Bis-tris (Sigma B-7535) 50 mM Tris (Fisher Scientific BP152-5) 50 mM Glycerol (Fisher Scientific BP229-1) 10% (v/v)

[0628] Methods

[0629] All assays were performed using pNPP or FDP as substrate. The optimum pH was determined for each PTP used.

[0630] PTP Assay

[0631] PTPase activity was assayed at 25° C. in a 100-μl reaction mixture containing an appropriate concentration of pNPP or FDP as substrate. The reaction was initiated by addition of the PTP and quenched after 10 min by addition of 50 μl of 1N NaOH. The non-enzymatic hydrolysis of the substrate was corrected by measuring the control without the addition of the enzyme. The amount of p-nitrophenol produced was determined from the absorbance at 410 nm. To determine the kinetic parameter, Km, the initial velocities were measured at various substrate concentrations and the data were fitted to the Michaelis equation where velocity=(Vmax*[S])/(Km+[S]), and [S]=substrate reaction concentration.

[0632] Inhibition Studies

[0633] The effect of the compounds on PTP was evaluated at 25° C. using pNPP or FDP as substrate. PTP was pre-incubated for fifteen minutes with various concentrations of compound. Substrate was then added at a fixed concentration (usually equal to the Km previously calculated). After 10 minutes, NaOH was added to stop the reaction. The hydrolysis of pNPP was followed at 410 nm on the Biotek Powerwave 200 microplate scanning spectrophotometer. The percent inhibition was calculated as follows: Percent Inhibition=[(control signal−compound signal)/control signal]×100%. The IC₅₀ was then determined by interpolation of a percent inhibition versus compound concentration plot.

[0634] Plasmids designed for bacterial GST-PTP fusion protein expression were derived by insertion of PCR-generated human PTP fragments into pGEX vectors (Pharmacia Biotech). Several of these constructs were then used to subclone phosphatases into pFastBac-1 for expression in Sf-9 insect cells.

[0670] Assay Methods in Determination of Compound-PTP IC₅₀: Fluorescent Substrate

[0671] The following in vitro assay procedure is preferred to determine the level of activity and effect of the different compounds of the present invention on one or more of the PTPs. Similar assays can be designed along the same lines for any PTP using techniques well known in the art.

[0672] The catalytic assays described herein are performed in a 96-well format. The general procedure begins with the determination of PTP optimal pH using a three-component buffer system that minimizes ionic strength variations across a wide range of buffer pH. Next, the Michaelis-Menten constant, or Km, is determined for the substrate 6,8-difluoro-4-methylumbelliferyl phosphate (DiFMUP). This Km value is subsequently used as the substrate reaction concentration for compound screening. Finally, the test PTP is exposed to varying concentrations of compound for fifteen minutes and allowed to react with substrate for ten minutes. The results are plotted as percent inhibition versus compound concentration and the IC₅₀ interpolated from the plot.

[0673] The following materials and reagents were used:

[0674] 1. Assay Buffer was Used as Solvent for all Assay Solutions Unless Otherwise Indicated. Component Concentration Acetate (Fisher Scientific A38-500) 100 mM Bis-tris (Sigma B-7535) 50 mM Tris (Fisher Scientific BP152-5) 50 mM Glycerol (Fisher Scientific BP229-1) 10% (v/v)

[0675] Methods

[0676] All assays were performed using DiFMUP as substrate. The optimum pH and substrate K_(m) was determined for each PTP used.

[0677] PTP Assay

[0678] PTPase activity was assayed at 25° C. in a 100-μl reaction mixture containing an appropriate concentration of DiFMUP as substrate. The reaction was initiated by addition of the purified PTP and quenched after 10 min by addition of 1% H₂O₂/100 mM NaCCl. The non-enzymatic hydrolysis of the substrate was corrected by measuring the control without the addition of the enzyme. The amount of DiFMU produced was determined from the increase in the fluorescence (360 nm excitation/460 nm emission) over that of background in the absence of PTPase. To determine the kinetic parameter, Km, the initial velocities were measured at various substrate concentrations and the data were fitted to the Michaelis equation where velocity=(Vmax*[S])/(Km+[S]), and [S]=substrate reaction concentration.

[0679] Inhibition Studies

[0680] The effect of the compounds on PTP was evaluated at 25° C. using DiFMUP as substrate. PTP was pre-incubated for fifteen minutes with various concentrations of compound. Substrate was then added at a fixed concentration (usually equal to the Km previously calculated). After 10 minutes, the reaction was quenched. The hydrolysis of DiFMUP was followed as described above. The percent inhibition was calculated as follows: Percent Inhibition=[(control signal−compound signal)/control signal]×100%. The IC₅₀ was then determined by interpolation of a percent inhibition versus compound concentration plot.

[0681] Plasmids designed for bacterial GST-PTP fusion protein expression were derived by insertion of PCR-generated human PTP fragments into pGEX vectors (Pharmacia Biotech). Several of these constructs were then used to subclone phosphatases into pFastBac-I for expression in Sf-9 insect cells. Oligonucleotides used for the initial amplification of PTP genes are as described above. The cDNAs were prepared using the Gilbo BRL superscript preamplification system on RNAs purchased from Clontech.

[0686] Materials and Reagents

[0687] Reactions are performed in Wallac 96-well polyethylene terephthalate (flexi) plates (Wallac, #1450-401). The detectable label is Amersham Redivue [γ³³P] ATP (Amrershan, #AH 9968), and the beads are Amersham streptavidin coated polyvinyltoluene (SPA) beads (Amersham, #NIF 1077) which are purchased from the commercial suppliers as indicated. The SPA beads should be reconstituted in phosphate buffered saline (PBS) without magnesiun or calcium, at 50 mg/ml, and stored at 4° C. prior to use.

[0688] Tris buffer, at 1 M, pH 7.4 is prepared by mixing approximately 70 ml dH₂O is added to a 250 ml beaker to which 12.11 grams of Tris is added. When the solid Tris has dissolved, the pH is adjusted to 7.4 with HCl. The buffer is then transferred to a 100 ml graduated cylinder and the volume brought to 100 ml with dH₂O.

[0689] Magnesium chloride (MgCl2) is prepared in a 1 M stock solution by mixing 20.33 grams of commercially available reagent grade MgCl2 with 100 ml of dH₂O. Once dissolved completely, the 1 M MgCl2 solution is stored in small aliquots at −20° C.

[0690] A stock solution of 1 M Dithiothreitol (DTT) is prepared as follows. 15.42 grams of DTT is added to 100 ml dH₂O, dissolved and stored in small aliquots at −20° C. This reagent can be stored in small aliquots to be taken out just prior to use.

[0691] PBS is purchased from a commercial supplier (Gibco BRL, #14190-144), or prepared without magnesium or calcium. The individual reagents are available from commercial suppliers such as Gibco BRL, and are prepared as follows: Molecular 10X Stock Ami. per 1X Reaction Reagent Weight Concentration Liter Concentration KCl 74.56 27 mM 2.013 g 2.7 mM KH2PO4 174.18 11 mM 1.916 g 1.1 mM NaCl 58.44 1.38 M 80.65 g  138 mM  Na2HPO4 141.96 81 mM 11.50 g 8.1 mM

[0692] 1 liter of 10× PBS is prepared by: 1) adding approximately 900 ml dH₂O to a graduated cylinder; 2) adding the reagents listed in the above table to the dH₂O; 3) when all reagents have dissolved, the solution is adjusted to pH 7.2 with HCl and the volume is brought to 1 liter with dH₂O. PBS can be left at room temperature, but 4° C. is preferred.

[0693] 10 ml of kinase buffer is sufficient for approximately 4.5 assay plates. Kinase buffer is prepared as follows: Stock Working Reagent solution Amount per 10 ml Concentration dH₂O 55.5 M   9.1 ml Tris pH7.4 1 M 0.5 ml 50 mM MgCl2 1 M 0.2 ml 20 mM NP40 10% 0.2 ml 0.2% *DTT (add fresh) 1 M 0.02 ml   2 mM

[0694] Non-radioactive adenosine-5′-triphosphate (ATP) from Equine muscle (Sigma, #A-5394), is preferably stored as a 10 mM stock solution at −20° C. To make 10 mM Stock solution, add 5 ml of dH₂O to 27.5 mg ATP and vortex. Any milligram amount of ATP can be used provided it is kept in the same ATP to dH₂O ratio. This reagent can be stored in small aliquots to be taken out just prior to use.

[0695] Ethylenediamine-tetraacetic acid (EDTA) is prepared by adding approximately 70 ml dH₂O to a 250 ml beaker. Then, 14.12 grams of EDTA is added to the beaker. Next, the solution pH is adjusted by adding 10 N NaOH drop-wise to the beaker, EDTA will dissolve at approximately pH 7.0. When the EDTA dissolves, the pH will fall, thus, NaOH need be added until the pH stabilizes at pH 8.0. The volume is then brought to 100 ml with dH₂O.

[0697] Procedure

[0698] Solutions of phosphate mimics or inhibitors are prepared at 4× the desired final concentration in 20% DMSO and 10 μl is added to each well. For positive and negative controls, 10 μl 20% DMSO is added to a well without the phosphate mimic or inhibitor. The peptide substrate (deb-tide) is diluted 1:250 with dH₂O to make 0.02 mg/ml. Make at least 600 μl per plate. The stock solution is diluted from a 10 mM stock 1:100 in water to make 0.1 mM. The following mixture is prepared for each plate:

[0700] 2) 24 μCi γ³³P ATP

[0701] 3) dH₂O to 600 μL.

[0702] The diluted peptide and ATP solutions are mixed 1:1 (600 μL+600 μL per plate), and 10 μL of the mix is added per well. The final concentrations are 0.5 μM cold ATP, 0.1 μg/well of peptide substrate, and 0.2 μCi/well of radiolabeled ATP.

[0703] 5 μL of cdk2/cyclin A is diluted into 2.1 ml 2× kinase buffer for each plate. 20 μL cdk2/cyclin A mixed with the kinase buffer is then added to each well. For negative controls, 20 μL 2× kinase buffer without cdk2/cyclin A is added.

[0704] The reaction mixture is briefly shaken on a plate shaker and then incubated 60 min. Finally, 200 μL stop solution per well is added and let stand at least 10 min. The plate is then spun approximately 2300 rpm for 10-15 min. The plate is then counted on a Trilux reader under standard conditions.

[1055] A stock solution of 0.2 M HCl is prepared as described above, and stored at room temperature.

[1056] Procedure

[1057] Coat ELISA plates with 2 g Poly((Glu,Tyr)) in 100 l PBS overnight at 4 degrees (PolyEY stock 1.0 mg/ml in PBS at −80). Block plate with 150 l of 1% BSA/PBS for 60 min. Wash plate twice with PBS, once with 50 mM Hepes buffer pH 7.4 (Using Titertek Washer MRD8). Plates can sit in HEPES buffer if other buffers need to be prepared. The Kinase Dilution Buffer, ATP mixture, negative control mixture, and TBS-W should all be prepared before proceeding.

[1058] Add 50 l of diluted kinase into all wells (Using Titertek Multidrop S20 Stacker). Purified kinase is diluted into “Kinase Dilution Buffer” to achieve a concentration of 10 ng/well. (Concentration of present purified kinase batch is 0.2 mg/ml)

[1059] Add 25 l drugs (in 4% DMSO) or DMSO controls (4% in water) to plate (Using Rapid Plate-96 Zymark). If starting with a 10 mM stock of compound in 100% DMSO, make a 25 fold dilution into water. The concentration of the drug dilution plate will be 400 M in 4% DMSO. If creating serial dilutions, dilute in 4% DMSO/water down the drug plate. Final compound concentration (highest) in the assay plate will be 100 M in 1% DMSO.

[1060] Incubate the kinase/compound mixture for 15 minutes. Add 25 l of 0.5 M EDTA to the negative control wells.

[1061] Reaction Step

[1062] Add 25 l ATP/MnCl2 mixture to the all wells. The reaction time is 5 minutes and is the most critical part of the assay. This is a fast kinase reaction and assay must be stopped with 25 l 500 mM EDTA in a manner similar to the addition of ATP. Fill and label this basin now, so it is easily available for kinase reaction termination. Wash plate 3× with TBS-W.

[1069] The reactions are performed in Corning 96-well ELISA plates (Corning, #25805-96) and the substrate is Poly (Glu,Tyr) 4:1, lyophilized (Sigma, #P0275). Poly (Glu,Tyr) is prepared at a concentration of 1 mg/ml in sterile PBS and stored in 1 ml aliquots at −20° C. Preparation of poly (Glu,Tyr) (pEY) coated assay plates is as follows: Coat 2 g/well of poly (Glu,Tyr) (pEY) in 100 l PBS at room temperature for 2 hours or +4° C. overnight. Cover plates well to prevent evaporation and store at 4° C. for not more than 7 to 10 days for best results.

[1072] Procedure for making a 1× working solution of TBB:

[1073] 1) To a 1 liter graduated beaker add approximately 900 ml dH₂O

[1074] 2) Add all reagents except the BSA

[1075] 3) When all reagents have dissolved, pH to 7.2 with HCl

[1076] 4) Add BSA, stir until dissolved.

[1077] 5) Bring volume to 1 liter with dH₂O

[1078] 6) Filter the solution to remove any particulate matter, and store at +4° C.

[1079] A 10× stock solution can be made by multiplying the amounts by 10 (but keeping the final volume of 1 liter). This stock is then diluted 10 fold with dH2O. Filter the solution to remove any particulate matter, and store at +4° C.

[1080] A 1% BSA stock solution is prepared in PBS, as described above, and stored at 4° C. In addition, a stock solution of 50 mM Hepes pH 7.5 is prepared as described above.

dH2O+4% DMSO

[1082] To make 10 mM Stock solution of ATP: 1) Add 5 ml of dH₂O to 27.5 mg ATP; and 2) Vortex. Any milligram amount of ATP can be used provided it is kept in the same ATP to dH₂O ratio. This reagent can be stored at −20° C. in small aliquots to be taken out just prior to use and kept on ice.

[1083] A stock solution of 1 M MnCl2, and working concentration of 40 mM MnCl2 are prepared as described above.

[1084] Kinase Dilution Buffer (KDB) is prepared as described above. 100 ml of kinase buffer mix is enough for approximately 40 assay plates.

[1085] The reactions are performed in NUNC 96-well V bottom polypropylene plates (Applied Scientific, #AS-72092). EDTA is prepared as described above.

[1086] The 1° and 2° antibodies are diluted in the Antibody Dilution Buffer which is prepared as follows: Stock Amount per Working Reagent solution 100 ml Concentration PBSTw 89.5 ml Milk in PBS 5%  0.5 ml 0.025% Sodium 10 mM   1 ml 100 M Vanadate BSA in PBS 5%   10 ml  0.5%

[1087] The antisera are as described above: anti-phosphotyrosine rabbit polyclonal antisera; Biochemistry lab, and goat anti-rabbit HRP conjugate (Biosource, #A110404).

[1088] The ABTS solution is prepared as described above, and kept in the dark at 4° C. until ready to use. Hydrogen peroxide 30% solution (Fisher, #H325) is prepared and is stored in the dark at 4° C. until ready to use

[1089] ABTS/H2O2 is prepared by mixing 15 mls ABTS solution with 3 l H2O2. The ABTS is warmed to room temperature about one hour prior to use. Or warm quickly by placing tube in 37 0 C water bath. Add 3 l H2O2 prior to use, and 0.2 M HCl which is stored at room temperature.

[1090] Procedure

[1091] Coat Coming 96 well ELISA plates with 2 g of polyEY peptide in sterile

[1092] PBS, as described above. Remove unbound liquid from wells by inverting plate. Wash 1×TBSTw. Pat the plate on a paper towel to remove excess liquid. Add 100 l of 1% BSA in PBS to each well. Incubate for 1 hr. at room temperature, with shaking. Repeat coating step.

[1093] Soak wells with 50 mM Hepes pH7.5, using approximately 150 l/well. Dilute drugs/extracts at 4× the desired final assay concentration in dH₂O+4% DMSO (unless specified otherwise) in 96-well polypropylene plates. Always add the larger volume of water to the smaller volume of compound to ensure rapid mixing. Add 25 l diluted drugs/extracts to ELISA plate. To control wells (wells which do not receive any drug) add 25 l of dH₂O+4% DMSO.

[1094] Dilute GST-Flk1 0.005 g (5 ng)/well in KDB. For 50 ml KDB add 100 l of 0.050 mg/ml GST-Flk1 enzyme. This is enough for 10 assay plate. (Check recommendations for each batch of GST-Flk) Add 50 l of diluted enzyme to each well. Add 25 l 0.5 M EDTA to negative control wells.

[1095] Add 25 l of 40 mM MnCl2 with 4×ATP (2 M ) directly to all wells. Approximately 100 l final volume in well with 0.5 M ATP final concentration. Incubate for 15 minutes while shaking at room temperature. After 15 minutes stop reaction with addition of 25 l of 500 mM EDTA pH 8.0 for 50 mM final in well.

[1096] Wash 3× with TBSTw and pat plate on paper towel to remove excess liquid. Add 100 l per well of anti-phosphotyrosine antisera (1:10,000 dilution in antibody dilution buffer). Incubate 90 min at room temperature, with shaking. Wash as described above.

[1097] Add 100 l per well of goat anti-rabbit HRP conjugate (1:6,000 dilution in antibody dilution buffer). Incubate 90 min. at room temperature with shaking. Wash as described above.

[1098] Add 100 l of room temp. ABTS/H2O2 solution to each well. Incubate 15 to 30 minutes while shaking. Remove any bubbles. If necessary stop reaction with the addition of 100 l of 0.2M HCl per well. Read assay on Dynatech MR7000 ELISA reader. Test Filter: 410 nM, Reference Filter: 630 nM.

[1099] 12. GST-FGFR1 Transphosphorylation Activity

[1100] Coat ELISA plates with 1 g Poly(Glu, Tyr) 4:1 (Sigma P0275) in 100 l PBS overnight at 4 degrees (Poly(Glu, Tyr) 4:1 stock 1.0 mg/ml in PBS at −20). Wash plate once with PBS. Block plate with 150 l 5% BSA/PBS for 60 minutes. Wash plate twice with PBS, once with 50 mM Hepes buffer pH 7.5.

[1101] Add 0.025 ml drugs (in 4% DMSO) or DMSO controls (4% in water) to plate. If starting with a 10 mM stock of compound in 100% DMSO then make a 25 fold dilution into water for the starting concentration in the drug dilution plate of 0.4 mM in 4% DMSO. Do serial dilutions down the drug plate in 4% DMSO/water. Final compound concentration (highest) in the assay plate will be 0.1 mM in 1% DMSO.

[1102] Add 0.05 ml of diluted kinase into all wells. Purified kinase is diluted into “kinase dilution buffer” (KDB):

[1103] For 25 ml: 2.5 ml 1 M Hepes (tissue culture stuff)

[1104] 0.1 ml 5% BSA/PBS

[1105] 0.01 ml 500 mM Na-orthovanadate

[1106] 0.25 ml 5 M NaCl

[1107] For GST-FGFR1 use 5 ng of purified protein per well. Concentration of present batch of purified GST-FGFR1 (917p79 Sep. 17, 1998) is at 85 g/ml. For one plate (120 wells for ease of pipetting) you will need 0.6 g (7.06 microliters) diluted into 6.0 ml of KDB.

[1108] Start kinase reaction with the addition of ATP/Mn++. ATP/MN is made at a “4×” concentration. For FGFR the 4× concentration is: 40 micromolar ATP/40 mM Mn in water. For 10 ml:

[1109] 0.4 ml 1 M MnCl

[1110] 40 microliters 10 mM ATP

[1111] 9.56 ml water

[1112] For negative controls, add Mn alone, with no ATP. Reaction time is 10 minutes. This is a fast kinase reaction-and assay must be stopped with 0.025 ml 500 mM EDTA in a manner similar to the addition of ATP. Wash plate 4× with TBSTween (0.05% tween20).

[1113] Detect with rabbit polyclonal anti-phosphotyrosine antisera at a dilution of 1: 10,000 into Antibody Dilution Buffer:

[1114] TBSTween containing

[1115] 0.5% BSA (i.e., 10 fold dilution of BSA block solution)

[1116] 0.025% nonfat dry milk (from 5% stock)

[1117] 0.01 mM Na-orthovanadate

[1118] 50 ml Antibody Dilution Buffer:

[1119] 5 ml 5% BSA

[1120] 0.25 ml 5% milk

[1121] 0.01 ml 500 mM Vanadate

[1122] brought up to final volume of 50 ml with TBSTween.

[1123] Use 0.1 ml per well. Incubate for 1 hour. Wash plate as above.

[1124] Dilute anti-rabbit HRP 1:6,000 in Antibody Dilution buffer. And incubate for 1 hour. Wash plate as above, follow with one wash of PBS to reduce bubbles and get rid of excess Tween-20.

[1125] Develop with addition of ABTS.

The culture medium is RPMI+10% FCS+L-Glu. There are two waterbaths, one at at 37° C. and another at between 42 & 44° C. Gilson pipettes/multichannel pipettes (or like) for dosing. A 2 l fixed volume pipette is useful to plate agarose microdroplets and appropriate sterile tips. Compounds for test are dissolved in 10 mM DMSO. Invert T.C. microscope fitted with an eyepiece graticule and calibrated with a stage graticule to allow accurate measurement of cell migration from origin to periphery of agarose microdroplet.

[1176] Procedure

[1177] Weigh 1 g Agarose to glass universal and add 50 mls PBS/A to give 2% stock agarose so in. Loosely fit lid and autoclave (with tips if required). Then keep agar stock in 4° C. fridge). Before use, microwave the stock at 50% power for 1-2 min to liquilize the agar stock and keep the agar at 42° C.

[1178] Trypsinize NCI H441 cells, (ATCC HTB 174) count for total cells (heamocytometer or coulter) and centrifuge to pellet. For each ml of plating solution (for agarose microdroplets) require:

[1179] 1.6×107 cells (as a pellet)

[1180] RPMI+10% FCS+L-Glu (at 37° C.) to 0.85 mls

[1181] 0.15 mls of 2% Agar stock solution (at 42-44° C.)

[1182] Resuspend cell pellet with required volume of medium at 37° C., transfer to a 7 ml sterile bijoux container add required agarose solution (gives 0.3% agarose conc. in microdroplets).

[1183] Quickly but carefully place 2 μl cell/agarose microdroplets approx. centrally in each well of the 48-well microtitre plates. Place lid on completed plate(s) and place on ice (or in fridge) for a few minutes to assist gelling of the agarose.

[1184] Very slowly pipette 90 μl of cooled medium (at 4° C.) into the wells of each microplate. A manual multichannel pipette is fine for this but our electronic pipettes are too vigorous even at the slowest setting and disturb the microdroplets.

[1185] Make growth medium with 400 ng/ml HGF and transfer (again slowly) 10 μl spikes to the test plates to make final 40 ng/ml of HGF. For negative control add 10 μl regular growth medium.

[1186] Transfer plates to 37° C. incubator for migration to occur. NCI H441 cells require approximately 40 Hrs before measurement.

An identical number of cells of the three cell lines should be seeded on three separate plates.

[1206] Make 2.5× of ligand medium ( containing FGF1 for R1 and R3, or IL-3 for FDCP), add 50 μl/well into the cells. Each plate should have its own positive and negative control (negative control wells receive medium alone without ligand).

[1334] Procedure

[1335] The cell line used in the following procedure is derived from a NIH 3T3 parental cell line: NIH/3T3 c7 Z3 a clone of 3T3 cells (CRL 1658).

[1336] Cells are seeded at 8000 cells/well in DMEM, 10% CS, 2 mM Gln in a 96 well plate. Cells are incubated overnight at 37° C. in 5% CO2. After 24 hours, the cells are washed with PBS, and then are serum starved in serum free medium (0° CS DMEM with 0.1% BSA) for 24 hours.

[1337] On day 3, ligand (LPA, prepared at 12.5 mg/ml in H2O, final LPA conc.=250 ng/ml) and test compounds are added to the cells simultaneously. The negative control wells receive serum free DMEM with 0.1% BSA only; the positive control cells receive the ligand (LPA) but no test compound. Test compounds are prepared in serum free DMEM with ligand in a 96 well plate, and serially diluted for 7 test concentrations.

[1338] After 18 hours of ligand activation, diluted BrdU labeling reagent (1:100 in DMEM, 0.1% BSA) is added and the cells are incubated with BrdU (final concentration=10 M) for 1 hour.

[1339] After incubation with labeling reagent, the medium is removed by decanting and tapping the inverted plate on a paper towel. FixDenat solution is added (50 l/well) and the plates are incubated at room temperature for 45 minutes on a plate shaker.

[1340] The FixDenat solution is thoroughly removed by decanting and tapping the inverted plate on a paper towel. Milk is added (5% dehydrated milk in PBS, 200 l/well) as a blocking solution and the plate is incubated for 30 minutes at room temperature on a plate shaker.

[1341] The blocking solution is removed by decanting and the wells are washed once with PBS. Anti-BrdU-POD solution (1:100 dilution in PBS, 1% BSA) is added (100 l/well) and the plate is incubated for 90 minutes at room temperature on a plate shaker.

[1342] The antibody conjugate is thoroughly removed by decanting and rinsing the wells 5 times with PBS, and the plate is dried by inverting and tapping on a paper towel.

[1343] TMB substrate solution is added (100 l/well) and incubated for 20 minutes at room temperature on a plate shaker until color development is sufficient for photometric detection.

[1344] The absorbance of the samples are measured at 410 nm (in “dual wavelength” mode with a filter reading at 490 nm, as a reference wavelength) on a Dynatech ELISA plate reader.

[1345] 27. Modulation of Tumor Cell Colony Formation

[1346] The following kinase assay provides a consistent method for measuring colony forming ability of tumor cells in soft agar upon activation or inhibition of a kinase.

[1347] Materials and Reagents

[1348] Soft agar: SeaPlaque Agrose, prepared at 1.2% in H2O, Autoclaved, refrigerated. Medium I: 2×DMEM+20% Fetal Bovine Serum+4 mM Glu, Medium II: 1×DMEM+10% Fetal Bovine Serum+2 mM Glu.

[1349] Procedure

[1350] Procedure for base plates: Have all media warmed to 37 C and dishes organized for plating. Melt agarose in a microwave (about 1 min on a high setting). Be certain to loosen the bottle cap. Let the agarose cool to about 37 C.

[1351] Mix 1.2% agarose 1:1 with Medium I to give 0.6% agarose in 1× medium. Dispense 0.5 ml/per well into 12-well plate to form a uniform base layer. Refrigerate base layers for 10 min to solidify. Keep the remaining 0.6% agarose solution at 37 C for making the top layer.

[1352] Procedure for Soft Agar Assay:

[1353] All tissue culture and plating is conducted aseptically in laminar flow hood. Sterile dilutions are prepared of each compound using Medium II. The initial concentration is 20-fold greater than the final assay concentration. Harvest the A431 cell by trypsin, and dilute an appropriate volume to give 6000 cells/ml in Medium II.

[1354] The Assay Mix is prepared by combining the following into sterile test tubes: 1) 0.48 ml cell suspension (6000 cells/ml); 2) 0.12 ml initial test compound dilutions in medium II; and 3) 0.60 ml 0.6% agarose, and a total of 1.2 ml cell compound mixture is used to add to two plates in duplicate. Approximately 0.5 ml of the Assay Mix is plated onto the 0.5 ml base layers. Dishes are refrigerated for 10 minutes to solidify the agarose. Approximately 0.5 ml of growth media that is added over the solidified agar layer. Dishes are incubated for 7 to 14 days in a 100% humidified, 5% CO2 incubator, and colonies that are 60 microns and larger are scored positive. The colony size is determined by visual judgment of colonies and visually counting colonies in each well, or by using colony counter.

[1355] 28. Flk-1 Phosphorylation Activity

[1356] The following kinase assay sets forth a method for testing the efficacy of Flk-1 modulators in vitro using a human umbilical vein endothelial cell line (HUVEC) that expresses the Flk-1 receptor.

[1357] Procedure

[1358] DAY 1

[1359] Wash flasks 2× with 7-10 ml PBS/75 cm2 surface area and aspirate after each wash. HUVEC cells are trypsinized with 2-3 ml/75 cm2 surface area 0.05% trypsin in cell dissociation medium (Ca++- and Mg++-free HBSS) for about 5 minutes at 37° C.

[1360] Approximately 10 ml per 75 cm2 surface area, of EBM medium (Clonetics, San Diego)+0.5% heat inactivated FBS (henceforth referred to as “assay medium”) and resuspend cells. Next, transfer the cells to a sterile centrifuge tube. An appropriate volume is taken for continued passaging of the HUVEC cells, and are placed in another centrifuge tube. Equal amounts of assay medium are added to each tube and centrifuged at 250×g for 5-10 minutes at room temperature.

[1361] The supernatants are aspirated and cells are washed prior to the assay 2× with about 30-40 ml PBS, each time-centrifuging and aspirating the supernatants. Plate the cells to be passaged in normal growth medium (EBM+2% FBS+1 g/ml hydrocortisone+50 g/ml gentamycin+50 ng/ml amphiteracin+24 g/ml protein from bovine brain extract+10 ng/ml EGF)

[1362] Resuspend cells in assay medium (10 ml/150 cm2 surface area of original flask from step A.1.); take 0.5 ml of the cells and add to a Coulter Counter cup with 10 ml counting medium. Count cells on the Coulter Counter and add assay medium to the cells to yield 5×104 cells/ml.

[1363] Pipet cells into a sterile pipetting reservoir. Using a multi-channel pipettor, add 100 l cells/well to sterile flat-bottom 96 well plates. If I have a steady stream of drugs to be tested, then I add all the cells available and whatever number of plates this results in is the number of plates I use for the assay. If there is a distinct number of drugs to be tested, you can estimate 4 drugs/2 plates (1 each for vascular endothelial growth factor (VEGF) and acidic fibroblast growth factor (aFGF)) for wells with ligand+12 drugs/plate for non-ligand control wells (1 column per drug), +2 columns for ligand dose curves. For example, if 8 drugs are to be tested, this would require 4 ligand plates+⅔ of a plate for controls (8 columns)+2 columns for ligand dose curves. This would necessitate almost 5 plates, or almost 2.5×106 cells (5×103 cells/100 l/well×96 well/plate×approximately 6 plates). Incubate plates overnight (20-24 h) at 37° C.

[1364] DAY 2

[1365] Make up working stocks of compounds. The compounds are in stocks of 20 mM (in DMSO), though some are at other concentrations. At 20 mM, the compounds are diluted 1:100 in assay medium to arrive at 200 M, which is a 4× concentration (i.e., it comprises ¼ of the total volume of the well and ultimately will be 50 M). Do not dilute any compound <1:50 as this may give a concentration of DMSO that may be detrimental to the HUVEC cells. Because of this, compounds that are relatively insoluble and are therefore in stocks of <20 mM will not be able to be used at as high a dose as the 20 mM compounds. Thus, a 2 mM stock can only be used at doses at 10 M or less (2 mM at 1:50=40 M which becomes 10 M upon completion of additional of material to the wells).

[1366] For each compound, 90 l/well are needed for 7 wells (3 each for VEGF and aFGF; 1 for non-ligand media control); thus make up at least 630 μl/compound. At 1:100 dilution (20 mM to 200 μM), this requires 8 μl/compound. Add 8 μl/compound to 792 μl assay medium in 2 ml screw-cap microcentrifuge tubes and vortex.

[1367] Since the compounds are in 1:100 DMSO:assay medium, a diluent of the same DMSO:assay medium ration needs to be make for the compound titrations. This is done so as to keep the DMSO concentration constant when diluting the compound. 60 μl/well will be needed, or approximately 6 ml/plate. In the example in A.9. where the set-up for an assay for 8 compounds is described, approximately 5 plates of DMSO:assay medium diluent is needed. At 6 ml/plate, this would require approximately 30 ml total. It is best to aim for a little more, e.g. 34 ml. At 1:100, 340 μl DMSO would be added to 33.66 ml assay medium to get 34 ml.

[1368] Titrate the compounds as follows:

[1369] a. Use new 96-well round-bottom plates to do the compound titrations.

[1370] b. Add 90 μl/well of the compound in the wells of the top row of a plate (row A). 4 compounds can be assayed/plate (3 column×1 ligand (VEGF or aFGF)×4 drugs=the 12 columns of the plate. Also add 90 μl/well to the top well of a designated column in the non-ligand media control plate(s).

[1371] c. Add 60 μl/well of the DMSO:assay medium diluent to the rest of the rows of the plates (rows B-H), but only where compound had been added to row A.

[1372] d. Make 3-fold dilutions by pipetting 30 μl of the 90 μl/well in row A into row B, making 90 l/well of compound that is 3-fold more dilute than the 60 μl/well remaining in row A. Pipet 30 μl of the 90 μl/well in row B into row C, making 90 μl/well of compound that is 3-fold more dilute than the 60 μl/well remaining in row B, and so on until row G. When the 30 μl of the 90 μl/well in row F have been mixed with the 60 μl/well in row G, take 30 μl/well out and discard; i.e. don't add to row H. Leave row H without any drug as the no-drug control. At the end of this pipetting cascade, you are left with 60 μl/well of 3-fold titrated compound. In the example in B.1. where 20 mM compounds are diluted 1:100 to 200 μM, giving 50 μM final concentration, the dilutions yield compound concentrations as follows: 50, 16.7, 5.5, 1.8, 0.6, 0.2, 0.07, and 0 μM

[1373] e. Transfer 50 μl/well of the 60 μl/well to the assay plate and incubate for 2-3 h at 37° C.

[1374] Add ligand (VEGF and aFGF) and media control as follows:

[1375] a. For each compound tested, 1.5 ml of VEGF and aFGF will be needed. This is because a separate volume of each ligand is needed per compound so that during pipetting of ligand, the previous compounds don't get mixed with subsequent compounds. 24 wells/compound will each get VEGF and a FGF. 50 μl/well of ligand will be needed, so 1.2 ml of VEGF and aFGF will be needed per drug. Since there will be some loss of volume due to surface tension in the pipetting reservoirs, 1.6 ml will be needed of each ligand. Thus in the example from A.9. where 8 compounds are tested, then 12.8 ml of each ligand is needed in total (1.6 ml/compound×8 compounds). For insurance, make a little more (14 ml).

[1376] b. For VEGF, the stock is 5 μg/ml, and the final concentration in the assay is 20 ng/ml. Since the volume of VEGF is ¼ that of the total assay (as with the compounds), a 4× concentration is needed (80 ng/ml). 5 μg/ml down to 20 ng/ml requires a 1:62.5 dilution, thus in the example in 5.a., a 1:62.5 dilution would require bringing 224 l VEGF up to 14 ml assay medium.

[1377] c. For aFGF, the stock is 10 μg/ml (as with VEGF), and the final concentration in the assay is 0.5 ng/ml. Since the volume of aFGF is ¼ that of the total assay (as with the compounds and VEGF), a 4× concentration is needed (2 ng/ml). 10 μg/ml down to 0.5 ng/ml requires a 1:5000 dilution. In the example in 5.a., just add 3 μl to 15 ml.

[1378] d. In the wells that had compound added earlier, add 50 μl of VEGF (or aFGF) to columns 1-12, except the media control wells in plate 5, which get 50 μl/well of assay medium. In addition, do not put ligand in wells H7-12; add assay medium instead. These wells will be the no drug/no ligand (negative ligand control) wells, and wells H1-6 will have no drug, but will have ligand (positive ligand control). These wells will be necessary in order for the Superb program to calculate the results.

[1379] e. Incubate plates overnight (20-24 h) at 37° C.

[1380] DAY 3

[1381] Add BrdU, (20 μl/well, 10 μM final concentration) and incubate overnight (20-24 h) at, 37° C. BrdU is made up in serum free F12K medium or F12K medium with 0.5% FBS.

[1382] DAY4

[1383] Perform BrdU ELISA as follows (all procedures are at room temperature):

[1384] a. Flick off medium from the assay plates and pat dry on paper towels.

[1385] b. Add 70 μl/well FixDenat (from Boehringer Mannheim) for 30 min.

[1386] c. Flick and pat as in a. above.

[1387] d. Add 100 μl/well 5% milk in PBS for 30 min.

[1388] e. Flick and pat as in a. above.

[1389] f. Add 80 μl 1:1000 (diluted in PBS+0.1% BSA) anti-BrdU (PharMingen) for 1 hour.

[1390] Lot to lot variability may require slightly different dilutions as recommended by the manufacturer (PharMingen)

[1391] g. Wash plates 3× in PBS.

[1392] h. Add 80 μl/well goat-anti-mouse horse-radish peroxidase for 1 hour; diluted 1:1000 in PBS+0.1% BSA. Tap plates gently to disperse liquid evenly in well. As in step f., lot to lot variability may require slightly different dilutions as recommended by the manufacturer (Southern Biotechnology).

[1393] 1. Wash 3× in PBS.

[1394] j. Add 100 μl/well ABTS substrate solution for 15-30 min. Before use, add 2 μl H2O2 for every 10 m ABTS to be used. Tap plates gently to disperse liquid evenly in well. Read on the Dynatech MR5000 plate reader using BioCalc software and at 410 nm wavelength with 490 nm wavelength as reference.

Other assays known to those skilled in the art may be employed to ascertain the ability of the compounds of this invention. Those of skill in the art would appreciate that modifications can be made to the assays to develop equivalent assays that obtain the same result.
